Graphical interface (graphical User Interface, GUI)

X Window System
How many components can this architecture be divided into? is basically divided into X server and x client two components Oh! where x server is managing hardware, and x client is an application.

The remote server is providing X client software

X server: Hardware management, screen drawing and providing font functionality each client host needs to have X server installed, while the server side provides x client software to provide the data data needed for client drawing

Because the purpose of x client is to produce the data of the drawing, we also call x client x application (x application).

As an example, when we move the mouse to the right in the X window screen.
First, X server detects the movement of the mouse, and x server informs the X Client of the action of the mouse,
The X Client will be calculated, and the result will be! To move the mouse pointer to the right several pixels,
This result is then communicated to X server,
You'll see X Server move the mouse pointer to the right.

Windows Manager (WM, window manager)
Window manager is also X client
Under Linux, each set of Window Manager (KDE, GNOME, XFCE,TWM) is unique, not the desktop and display, but even the engine will not be the same Oh!

X server/x Client/window Manager is present on one of our Linux hosts

STARTX command
[[email protected] ~]# startx #禁止再当前tty上执行, otherwise the underline input cursor will always be displayed in black screen
[[email protected] ~]# STARTX [x client Parameter]--[x Server parameter]
# example: Start X with a color depth of
[Email protected] ~]# startx---depth 16

Find/-name ' XSERVERRC '

~/.xserverrc
/etc/x11/xinit/xserverrc
/usr/bin/x #会读取/etc/x11/xorg.conf configuration file

~/.xinitrc
/ETC/X11/XINIT/XINITRC #将会引入/etc/x11/xinit/xinitrc-common (real do not exist),/etc/x11/xinit/xclients,/etc/sysconfig/ Desktop (does not exist) three files
Xterm

Xinit command
[Email protected] ~]# xinit [client option]--[Server or Display option]

[Email protected] ~]# xinit #相当于: Xinit xterm-geometry +1+1-n login-display:0--x:0
In the X client side: The xterm is the virtual terminal under the X window, and the parameters behind it are the location of the terminal and the login or not.
The final side will be followed by a "-display:0 "Indicates that this virtual terminal is launched in the" section: 0 The X of the number shows the meaning of the interface ".
As far as X server is concerned, the X server program we started is x! In fact, X is the connection file of Xorg, which is the main program of x server! So we started x pretty simple-just execute x, and also specify X to start at: 0 X display interface.


The relevant display module, or the total total module mentioned above, is mainly placed in the/usr/lib64/xorg/modules
? The screen font provided:/usr/share/x11/fonts/
? Display adapter's chipset:/usr/lib64/xorg/modules/drivers/

/etc/x11/xorg.conf, real does not exist, there is/etc/x11/xorg.conf.d/00-keyboard.conf


[Email protected] ~]# xrandr-s 1280x800 #字母X. Real: The results of the previous "Xrandr" command did not show 1280x800 resolution, so this resolution is not available
Size 1280x800 not found in available modes


Adapter driver Installation
